摘 要：Asynchronous rolling technology was adopted for the accumulated ten passes cold rolling, flange plate steel, and for welded H section steel, respectively. The metallographic microstructure analysis, tensile test and annealing test were carried out for cold rolled pieces; thus the ratio of length to width of grain, tensile strength, relationship between the grain size and asynchronous rolling process parameters after annealing can be obtained. The experimental results show that the relationship between the asynchronous rolling and the shearing deformation of rolled pieces can make a reasonable interpretation of the mechanism that asynchronous rolling may improve the strain accumulated energy of rolled pieces and the strength of flange plate steel. This paper provides a theoretical basis for the application of asynchronous rolling in improving the strength of flange plate steel.
